This invention relates to certainnew and useful improvements in exterminators ofthe type adapted to bedrawn past growing plants and vines andhaving means for extractin bugs, insects, and other parasites therefrom onto a collector and from'th'ere conveyed to crushing or other destroying means p In my Letters Patent numbers 1,239,799

and 1,264,19hissued the 11th dayof Sep tember, 1917 and the 30th day of April, 1918, s

respectively, exterminators of a character similar to the oneforming the subject matter of this application are shown. and'described. The exterminators of said Letters Patent, howeverthough: successful in operation, are open to several objections among which may be noted their numerous parts andrexcessive weight, and theconsequent high cost of production, that the same are capable of handling but a single row of plants at onetime and further, require more than one horse or other draft animal to draw the same.

It is a further object of thisinvention to greatly improve and simplify the construction of exterminator-s of the character described and to increase their efiiciency whereby twicethe amount of work can be accomplished at a reduced cost of operation, in that but a single draft animal is required to pull the same.

Another object of thisinvention resides in I the provision of an improved exterminator of the character described, the construction of which is so simplified and flexible that the handling thereof iscomparativcly easy and at the same time the operation thereof in very reliable. f 1

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement'of parts substantially as hereinafter described and more particularlydefined by the appended claims, itbeing understood that such changes in the'precise embodiment of the herein disclosed'inventionmay be made as come within the scope of theclaimsl In tlie'accom 'ianying drawings, I have illustrated one complete example o'l th physical embodimentof my invention constructed according to, the best mode I have solar devised for the practical application ofthe principles thereof, and in which i I Figure lisa side view, partlyin elevation and partly n sect1on,'of an exterminator embodying liny invention, said view'bein'g through Figure Zion the plane of the :line' 11; o i I I t Figure 2 is a transverse sectional view, witlrparts in elevation, taken through Figure 1 on the plane of the line 2-2 and looking toward the 'forwardportion of the machi11 I f 1 or Figure3-is a Figure 4 is a view,-partlylin sectionand partly in elevation, and with parts of the mechanism removed or broken away, taken transversely through Figure2 on the plane oftlleline lfl; \iv Figure 5 is a fragmentary view,partly v v view, partly invsection and partly in elevatiomand taken transversely 1 in "sectionand partly in'sidee elevation, of I the bug scraper or Conveyerand crushing i means, said'viewrbeing taken through Figure 3 on theplane ofthe line 55;.

I Referring now more particularly to the accompanying drawings, in which like nui merals'designate like parts throughout' the mounted to travel uponwheels 6 and 7 and several views, 5 designates a mainframe which 1 may be drawn or propelled by a a single draft animal or a tractor mechanism ofany suitable type. The frame 5broadly consists of two side sills or beamslS preferably formed of angle iron and having one end "(IlII'GCtGCl downwardly vto form vertical legs '9 which'are connectedat their'ends by 1 I anjaxle 10 projecting beyond the frame to mount ,theiwheels 6 and 7 The beams 8 are connected at their rear-most endsiadjacentthe legs 9oby a tie or brace member 11 on which is cen'trally'mounted a pair of vertii guidepulley ltbeing journaled between the I a guides 12 at their upper ends for the purpose later described. I j V A pair of spaced standards 15, substan-v tially complementary to the guides 12 and in longitudinal alignment therewith, are mounted adjacent the forward endof the main frame and have their lower end portions directed laterally as at 16, and secured to the beams 8, as at 17, the standards 15 with their lateral .members 16being preferably formed from a single length of strap metal bent to form. The guides 12 arelikewise, formed from a single length of strap metal; nAs it is essential that the space between'the, guides 15 be'open at the bottom, the lateral end. portions 16 thereof. are of necessity relatively long and to provide'the ,Tproper rigidity for theguides, a pair ofdi 7 agonal braces 18 are extended from their uppenends-to the beams 8, to which. they aresecured by the means 17 and additional diagonal braces 19 extend from the upper portionsof the guides to atransverse beam 20 connecting the, beams 8 adjacent their forward, ends and with which the usual draw :ba'r'21 is connected by a ,pin '22, sills 23 be,-

ing suitably secured to the forwardportions of the beams 8 extendedbeyond the transverse beam 20. The guides 12 and 15 are o shownin'lfigure 1.:

further braced and held in their proper spacedrelatio'n by a connecting strap or brace 24 secured to'the tops thereof as best members 26 forming guides adapted to move into thejspace 'bet'ween t-he guide members 15' of' the'main' frame. The lower ends: of

. theverticalmembers 26 are inclined downwardly and outwardlyfas at 27, to mount the supporting beams or sills of the bugconveying and crushmg mechan sm, the members 26 preferably being formed from a length ofstrap metal extending beneath the beams 28. .The rear ends of the side members of the diamond shaped frame 25 are secured to a pair of vertical suspension members 29 preferably formed inone piece and extendingunder the beams 28 to support the "rear thereof. I The upper ends of the i 1 members 29 are secured to the ends of the side members of the framez25, as at 30, and are connected by a pair of brace members 31having their innerfends directed upwardly, as at 32, torreceive the rear end of a medial. brace 33 therebetween, the forward end of-which; is secured between the guides 26 at their upper ends; 'An attachinghoolr "nected' with the end 38 of a lever 39.

above the brace 33 toreceive the end 35 of i a lifting chain or cable'3G which is trained over the pulley rlelmand has its end 37 co pr. '11 attaching hook 40 is secured between the forward guides 26 and has the end 11 of a chain or cable 42 connected therewith which extends upwardly, and is trained over a guide or pulley 43 journaled: between the forward main frame guides15 and thenrearwardly being'trained over the rear guide pulley 14 with its endaasecured to the end 38 of the, lever '39.

The secondary .frame is braced at its forward end by adiagonal guides?) having its upperend connectechas at 46, with the central brace member 33 and its lower end connected at 47 between the forward guides 26, said diagonal brace being preferably integral with the attaching book 40. The rear portion of the frame'is braced by diagonal members 48 connected at their lower ends to the vertical members 29 and: at theirupper ends to the side members'of the frame 25. Connecting the sidcs of the frame 25 at its widest or central point is. a. transverse support member 49 the'ends of which are directed downwardly and secured to the frame at 50, said transverse member having two sets or series of apertures 51 therein to adjustably mount a pair of bearing members 52,-the securingscrews 53 ofwhich pass through the apertures giving the bearing members the desired adjustment. A pair of horizontal, axially aligned shafts 5a are journaledfone infeach bearing member 52,

the outer ends-of the shaftsfha-ving bevel gears 55 fixed thereon meshing with gears 56 fixed to theadjacent ends ofa pair of vertical shafts '57, the upper ends ofwhich are journaled in the: bearing members 52 as best illustrated: in Figure 2, and. the lower ends of; whichhave spiders 58 adjust-ably mounted thereon, as later described. The shafts 54 areadjustably'connected by a tubular shaft 59. in which their adjacent ends are adjustably secured by bolts or other means 60 so that the gears 55; are driven in unison from a sprocket member 61 fixed on from the wheels Sand 7 in. the manner later described. The spiders 58 each have a pluthe tubular shaft 59 and adapted to be driven o ralityof laterally extended arms 62 on thcouter ends of which brooms. orbrushing members 63are secured, the present embodiment illustrating the mounting of four brushing members from each spider 58. The adjustable mounting of-the spiders 58 on their respective shafts permits the brush-cs to be raised or lowered according to'the size of the plants.

The sprocket member 61 derives its driving power from a shaft 64 carried by the" main frame and extended transversely there.-

of with its end portions *journaled in bearmgs secured to diagonal braces 66 coir necting the vertical legs and horizontal,

beams ofcthe main l rameythe shaft 64 in turn being drivenffrom thewhecls 6 and '7 through sprocket wheels ,67 freely journaled on said shaft connected withdriver sprockets 68 in drive connectionwith the wheels through a sprocket'chain G9. The shaft 64 is adapted to be drivinglyQconnected or disconnected from'the driven sprocketpwheels 67 tl'iroug'h clutch members 70 fixed thereon, the sprocket wheels being engaged or disengaged from the clutch members by operating levers 71 which are engageable behind stops 72 (see Figure 4) tothold the same in engagement with the clutch members against the action of springs 73 which normally tend to disconnect and render the drive inoperative.

The shaft 64 is drivingly connected with the shaft of the bevel pinions 55, by a sprocket chain 74 train-ed about'a sprocket wheel fixed to the shaft 64 and the sprocket wheel 61, there being a novel slack, adjuster for the chain 74-to automatically lengthen or shorten the chain 74 as the secondary.frame is raised or lowered, respectively.

Thus it will beseen that with the clutch members 70 in operative connection with their sprockets 67, the brooms or brushing members 63 are'rotated to advanceinwardly at the forward part of the machine and reaching out beyond the machine in the manner illustrated in Figure 2 brushing the plants or vines, as" indicated at 376, "and knocking the bugsandother parasites therefrom onto a collector, to be later described, which in turn conveys the bugs to a crushing means. i c I Q As stated above, the convcyer is: mounted from the lowerport-ion ,(of the secondary frame and its frame is formed bytheangle members 28 together, withthe transversely extcndedportions of the members 26 and 29, and consists of a plate 77 connecting the anglemembers 28ovcr which the conveying mechanism proper ivorksw The conveying mechanism proper includcsaepair of spaced, horizontal rodsT 8 having their rear portions bent upwardly, horizontally candjuthen downwardly, as at T9, to accommodate a crushing roller 80, to be later described, and on which a seriesol sleeves or bushings 81 are secured to form spacing members for a plurality of scrapers 82 supported from the rods, a screen or other,foraminous member 83 being suitably'seeured to the top of the scraping members, for the purpose later de scribed. I m 1 I The rear ends of the rods 7 8 are secured at 84 to a scraper 85 working rearwardlyof thecrusher 80 and to a pairot' suspending links 86, the upper ends of which are aper tured to slidably receive a pair of lifting levers 87c fixedto a cross bar 88 connected at ,89 with the vertical portions of a pair oi sequently thescraping mechanism, aresupported from the forward end of the frame 25 by a pair of suspension rods having their upper ends adjustable, as as 96, in a bracket member 97 pivoted to the frame 25 and their lower ends connected to a trans verserodor shaft 98 to which is secured a paired. bell cranks99 havingthe outer ends of their horizontal arms connected at 101 with 'one' of the'forward scrapers 82 andthe outer ends of their vertical arms 102 adjust-ably connected at 103 with atransversely disposed angle iron mempivotally her 104, whereby the rocking ofithe bell cranks 99 to lower their arms' l00 lowers the forward end'of the scraping mechanism to' engagement with the plate 77' and raising Wltlltllfi plate 77. A connection between the angle lron member 104 and the transverse thereof elevates the scrapers from contact member 8 pel'atesthe levers 87in unison withthe bell cranks 99 so that the scraping mechanism is elevated and lowered horizontallyflto' cause the scrapers :82 to simultae neouslyengage' and disengage the plate 77, the connection being made by a 'rod'or link 105 connected at its rear end with the transve1'se-1nember88,'as at 106, and having its forward end passed through an aperture in the angle iron -104'withstops 107 on opposite sides thereof toafiord a certain amount of lost, motion to accommodate the excess movement of the vertical arms of the bell cranksv 99 which are longer'rthan those ofthe bearing members '90, i l The bearing members 90 and the bell cranks 99 thusjaitord meansqfor simultaneously raising and loweringboth ends of the, conveyingscrapers and means are operable from the drive shaft 64 to ireciprocate the scrapers and elevate the same when they reach their rearmost limit of movement and lower, them into engagement with the plate 77' when they reach'their. forward limit ofmovement.;i J p m ,Thereciprocation of the scrapers is effected through an eccentric 108 liked to the shaft 64 and with which the rear end of a pitman "109'is connected bya ring 110, the

pitman having its forward end connected, as" at 111, with a transverseboltor pivot 112 passed through the upper end of-a vertical member or upright 113 carried by a bearing,

member 114 journaled on the 'shaft '98. A brace rod 115' is connected with r the upright 113 at an intermediatepoint and extends rearwardly having its rear end fixed to a bracket member 116 mounted on the transverse: member 92 so that, ass-the pitman 109 is moved forwardly by rotation of eccentric 108, the roller and conveyingmechanism is likewise] shifted forward and vice versa. Mounted on the shaft 64 and adjustably fixed with respect to the eccentric 108 is an ee- 7 centric 117 having a greater throw'than the eccentric 108 and set in advance'thereof and about which a strap or ring 118 is rotatable, a pitman 119 being connected with the'ring 118 the forward end of which is slidable in an aperture in the angle iron 104 and has a stop 120 thereon rearwardly of the angle iron and between which and the angle ironanexpansil. spring is confined.

The setting" of the eccentrics 108 and 11;?

' 'with respectto each othcris such that when the eccentric 108 causesthe conveying mechanism to reach its forward limit of movement, the eccentric 117 has retracted its pitman119 to permit the conveying scrapers to drop onto the plate 77,.the conveyer and crushing member SO'being then moved rearwardly. As the conveyer mechanism reaches its rearmost limit of movement, the eccentric 117 advances its .pitman 119 moving the angle iron 10, 4 forwardly, with respect-to the conveyer, elevating'the free ends of the lever 87 and the arms 1000f the bell cranks 99 to raise the conveying scrapers 82 prior to the, time the eccentric'108'moves its pit- ,man 109 forward in retrieving movement.

A seat 121 is supported fromcthevrear por-' tion of the main frame juxtap ose an operating lever 122 working in a quadrant 123 for actuating the lever,39 which effects the adjustment of the secondary frame in the main frame, a suitable detent 124 working on the quadrant to permit the setting'of the sec- 7 ondaryframe in any position.

hen the secondary frame isdown, a pin 125, (see Figure 7) may be inserted across the guides 15 above the upper end of they guide members 26-to hold the'sills 23 in approximately horizontal position and facilitate harnessing of a draft animal in place, after which the pin 12 51 is removed and inserted in anopening'126 in the transverse portion 16 of one guide member 15. The secondary frame is then adjusted to any desired P08111101! by the lever 122 assisted by a spring 127 which normally, exerts a tension to help support the weight of the secondary frame in the main frame. v

The device is'then drawn between adjarcentjrows of plants 76 with plant or vine guards 128 serving as guidesand riding on der any vines. or plants which may have fallen to raise them to a position where the brushes may properly engage the same. Each guard ,128 includes a'horizontal bar 129 pivotally supported from the angle members 28 by toggles 130 which normally incline rearwardly so'that an upward pull on'the forward end of the guard collapses the same against the adj acentmembers 28, there being a guard rod 131 extending rearwardly therefrom to assist in raising fallen vines.

Connectedwith the forward end of each vine guard at 132 is a control rod133, which is adjustably and pivotally connected, as at 134, with the forward end of a lever 135 medially pivoted on the tubular shaft- 59 adjacent the sprocket wheel 61. The rear end oflever 135 carries a pair of spaced guide pulleys 186 and 137 over which the sprocket chaini't is trained, a contractil spring 138 connected, as at 139, with the rear cnd'portion of the lever135 and with the mainframe, as at 1 10, normally maintains the chain'H: taut and tends'to extend the rod 133 to position the vine guard in lowered or active position. As the secondary frame is raised by'the manual operation of the lever 122 and the mechanisn'i controlled thereby and previously describechjthe distance be tween the shafts 64: and 59 increases causing the lever 135 to pivot and assume thepOs'i- 'tion illustrated in Figured exerting a pull on the rod 133 and drawing the vine guard to inactive position as illustrated; In this position, the device may be readily maneuvered and turned around without interfer ence withthe plants, etc.

, lVith the machine in active position, as illustrated in Figure 2, and the same advanced, the brooms or brushing members are rotated, in the manner described, striking the plants 76,"brushing the bugs'and other foreign matter therefrom and impelling the same onto the screen 83, the bugsfalling .act as a plow and prevent throwing of the bugs outwardly of themachine, and plates 14:4 are provided at the rear portion of the conveyer to further guard against overshooting of the bugs.- The partition 14121 is cut away at its forward end atltfi to accommodate" the longitudinal:shiftingof the convey er andthe mechanism for supporting the forward end thereof and this cut away portion is adapted to be closed by a plate 146 fixed to the rod 105 to reciprocate with the conveyer. I

As the bugs drop onto the plate 77, the

scraping'blades 83 advance them step by step towardthe crushing rollerand on the forward movement thereofcrushes the bugs advanced by the rearmost blades 83 and I the bugs-crushed thereby are moved rear- Wardly ahead of the roller on the next stroke.

thereof by'the scraper 85, mattervtcnding'to adhere to thecrushing roller being removed therefrom by a 'scraperfla'z'. Thusit will be seen that the scraper 85 clears the pathin back of the crushingmember as the crushing member kills'the' bugs previously placed in its path by the last scraper 82 and. at the same time thelast scraper 82 is conveying a fresh supplyof bugs toward the; crushing member to be crushed as it advanceson the next stroke. f r 1 x From the foregoing description taken in connectionwith the accompanying drawings,

it will be readily apparent to those skilled in the art tofwhich an invention of the char acter described appertains that I provide a greatly nnproved exterminator of the char- ZlCtOYtlGSCl'lbQClWlllCh is ad ustable to permit the use of the device with rows of vari-Y ous widths, which will handle two rows of plants where heretofore only one could be handled, which is of simplified structure,reducing its cost of construction and its weight and facilitatingits handling and which may be very conveniently handled by a single,

draft animal where heretofore more than one has been necessary.
